One of the provocative things about Cleo was the fact that you really couldn't tell if she was wearing clothing or not. She had a prominent fuzzy line along her thighs that made her look like she was wearing something like a swimsuit, but there were no other prominent clothing lines. Since clothing tends to begin and end in most cartoon model sheets, this led to her clothing wearing status being uncertain, quantum effects notwithstanding.

Clothing or not, her vast fluffy fur kept her looking decent. What's surprising, though, is that she doesn't have a greater following in furry fandom.
